You’ve landed in Lisbon for a three-month stay. Your iPhone supports eSIM. You bought a plan online before flying. Now you’re standing in arrivals, following activation instructions, and… nothing happens. Or worse: the QR code scans, the profile installs, but you have zero data. We see this scenario weekly with digital nomads who contact ConnectPls support after an eSIM provider let them down.

This guide walks through exactly how to activate eSIM on iPhone, what actually goes wrong in the field, and when a different connectivity approach makes more sense for the way digital nomads work and travel.

What You Need Before You Start

Not every iPhone supports eSIM. You need an iPhone XS, XR, or newer (including all iPhone 11, 12, 13, 14, and 15 models). The iPhone 14 and later sold in the US are eSIM-only with no physical SIM slot—international models still have both.

Your device must be carrier-unlocked. If you’re still paying off a phone through Verizon, AT&T, or similar, it’s probably locked. Call your carrier or check Settings → General → About → Carrier Lock. If it says “No SIM restrictions,” you’re clear.

You’ll also need the activation details from your eSIM provider: either a QR code, an SM-DP+ address and activation code, or (increasingly common) an app that handles installation. Make sure you have WiFi access when you start—airport or hotel WiFi works fine.

“We managed to stay always connected while travelling around Europe, without having to buy SIM cards in every country and ending up with a handful of them with different balances we couldn’t use. Excellent support team.”

Step-by-Step: Activating eSIM on iPhone

Method 1: QR Code Activation

This is the most common method. Your eSIM provider emails or displays a QR code after purchase.

• Open Settings on your iPhone
• Tap Cellular (or Mobile Data depending on region)
• Tap Add eSIM
• Choose Use QR Code
• Point your camera at the QR code (if it’s on another device) or tap Enter Details Manually if the code is on your iPhone screen—you’ll paste the SM-DP+ address and activation code instead
• Tap Add Cellular Plan when prompted
• Label the plan something useful (e.g. “Portugal travel” or “Work data”)
• Choose which line to use for cellular data and calls

The profile should install in 30 seconds to two minutes. Restart your iPhone if it doesn’t appear under Settings → Cellular.

Method 2: Provider App Activation

Some eSIM providers use an app to handle installation. You download their app, log in, and the eSIM profile installs directly without scanning anything. The process is similar—Settings → Cellular → Add eSIM—but the app pushes the profile to your device automatically.

Method 3: Carrier Activation (Converting a Physical SIM)

If you have a physical SIM from a carrier that supports eSIM, you can sometimes convert it. This is common with primary mobile contracts but rare with travel eSIMs. Go to Settings → Cellular → Convert to eSIM and follow prompts. This method doesn’t apply to most travel scenarios.

When Activation Fails: What Actually Goes Wrong

After three years shipping devices and supporting nomads across 160+ countries, we’ve heard every eSIM horror story. Here’s what breaks:

The provider’s network agreement is broken. You install the profile successfully, but the eSIM never connects to a local network. This happens when an eSIM reseller’s wholesale relationship with a carrier expires or changes. You’re stuck troubleshooting on their timeline, not yours.

Your iPhone is locked. The activation process completes, but the eSIM won’t activate because your device is still tied to your home carrier. This is especially common with US iPhones bought on installment plans.

The QR code doesn’t scan. Usually a problem with the image quality or your screen brightness. Try increasing brightness, zooming in, or switching to manual entry with the SM-DP+ details.

The plan activates but data is unusable. We see this with ultra-cheap eSIM providers who throttle speeds heavily or impose tiny daily caps that aren’t clear at purchase. A nomad working from a café in Barcelona doesn’t need 500MB—they need reliable bandwidth for video calls, cloud backups, and Slack all day.

eSIM vs Other Connectivity Options: What Works When

eSIM is one tool. It’s not always the right one, especially if you’re spending months in one place, working from a campervan across France and Spain, or bouncing between countries every few weeks. Here’s how the options compare for digital nomads:

Option	Best For	Limitations	Typical Cost
eSIM (travel provider)	Short trips, single-country stays, light data use	Single-device only, no backup if provider fails, often data-capped	£5–£15/week depending on country and data allowance
Local SIM card	Long stays in one country, local phone number needed	Requires local paperwork or purchase in-country, new SIM each country	£10–£30/month depending on country
Home carrier roaming	Very short trips, occasional use	Expensive, often throttled, surprise bills common	£5–£15/day roaming charges
Portable WiFi subscription	Multi-country travel, multiple devices, van life, monthly stays	Requires carrying a device (pocket-sized), monthly commitment	Monthly plans with included hardware, unlimited data in 70+ countries

Why Digital Nomads Choose Subscription WiFi Instead

At ConnectPls, we started offering eSIM plans because travelers asked for them. But most digital nomads who contact us end up choosing the mobile router subscription instead. Here’s why:

You’re not limited to one device. The router connects up to 10 devices—your iPhone, laptop, tablet, partner’s phone, backup devices. Most nomads carry at least three screens. eSIM covers one.

It works the day you arrive, guaranteed. The device ships to your address 2–3 working days across Europe, 4–5 days in the UK. You switch it on when you land. Cloud SIM technology connects automatically to local networks across 160+ countries without you configuring anything. There’s also a backup physical SIM slot if one network has poor coverage where you’re staying.

Truly unlimited data where it matters. The Plus Europe package is genuinely unlimited (no fair-usage throttling) across 70 Group 0 countries including the UK, Ireland, France, Germany, Spain, Italy, Portugal, Netherlands, the Nordics, Turkey, Canada, Mexico, Australia, and New Zealand. If you’re spending a month in Porto running a remote business, or van-lifing through France and Spain for the summer, you’re not counting gigabytes or buying top-ups.

Monthly billing with no traps. You activate for the months you’re traveling and pause when you’re not. No contracts. No surprise bills. There’s a £25 fee if you cancel a mobile-router plan in the first three months (it covers the shipping and return logistics of the included device), but after that, cancel anytime.

Compare that to hunting for reliable WiFi every time you change Airbnbs, or juggling eSIM purchases every time you cross a border, or finding out your eSIM provider’s network agreement expired while you’re mid-deadline on a client project.

When eSIM Actually Makes Sense

We’re not anti-eSIM. It’s a solid choice for specific situations:

• You’re traveling for a week or two and only need data on your phone
• You’re staying in one country with good eSIM provider coverage
• Your accommodation and coworking spaces have reliable WiFi, and mobile data is backup-only
• You want a second line for local calls without swapping your primary SIM

But if you’re working full-time on the road, spending months across multiple countries (like the classic Barcelona → Lisbon → Berlin circuit), or traveling in a motorhome where portable broadband is your only connection, eSIM’s single-device limitation and country-by-country purchasing creates friction you don’t need.

Troubleshooting Common eSIM Activation Problems

eSIM installed but no service: Check Settings → Cellular and make sure the eSIM line is toggled on and selected for cellular data. Go to Settings → Cellular → [eSIM line] → Network Selection and switch off Automatic—manually pick a network. Restart your iPhone.

“Unable to Complete Cellular Plan Change” error: Usually a server-side issue with your eSIM provider. Wait 30 minutes and try again, or contact their support. Sometimes the activation code has already been used or expired.

eSIM works but data is extremely slow: Your provider may throttle after a certain threshold, or the local network they’re using has poor coverage. Check if other carriers have stronger signal in your area, but with eSIM you’re locked to the provider’s network agreement. A Cloud SIM device automatically switches to the strongest available network.

How ConnectPls Works Differently (From Someone Who Ships Devices Daily)

We’re the team who packs the routers, answers the 2 a.m. “I’m in Bucharest and nothing’s working” support messages, and hears the relief when someone’s connection is back up in five minutes. That’s shaped how ConnectPls works.

The device is included in your monthly plan—you don’t buy hardware upfront. It arrives at your door before you leave. When you land in Spain, France, Portugal, Germany, or any of the 70 Group 0 countries, you turn it on and you’re connected. The Cloud SIM handles the network switching. If something’s not working, you message real support (our Google rating is 5.0, and travelers mention the 24/7 responsiveness constantly), not a chatbot.

If you’re van-lifing across Europe and need motorhome broadband for France and Spain that doesn’t reset every border, or you’re a freelancer doing monthly stays in different cities and tired of researching the cheapest pocket WiFi in Australia one month and portable WiFi in Spain the next, a flexible monthly subscription removes all of that overhead.

Frequently Asked Questions

Can I use eSIM and a physical SIM at the same time on iPhone?

Yes. iPhones with both eSIM and a physical SIM slot support dual SIM functionality. You can keep your home number on the physical SIM for calls and texts, and use the eSIM for data while traveling. You choose which line handles cellular data in Settings → Cellular.

Do I need to delete an eSIM before installing a new one?

No, but iPhones have a limit (around 8–10 eSIM profiles stored at once, though only one or two can be active simultaneously depending on your model). If you’re installing many travel eSIMs over time, you may eventually need to remove old profiles. Go to Settings → Cellular → [eSIM line] → Remove Cellular Plan.

What happens to my eSIM if I reset my iPhone or get a new one?

eSIM profiles are tied to your device. A factory reset deletes them. Upgrading to a new iPhone doesn’t automatically transfer eSIM profiles the way physical SIMs transfer by moving the card—you’ll need to reinstall or contact your provider for a new QR code. Some carriers support eSIM transfer during iPhone setup, but most travel eSIM providers don’t. This is another reason digital nomads who upgrade devices frequently prefer portable WiFi subscriptions. The router stays the same regardless of which phone or laptop you’re using.
